I hope your are all well

 

I wanted to know the possibility to configure an ASA NGFW cluster in transparent mode in the following context.

I started to work with the EVE-NG tool but I had problems activating the FTD interfaces, I can't put them up.

 

The objective is to filter only the traffic between the different subnet.

 

Thank you indvance for your help.

 

Regards.

But I was able to solve the access problem by adding this command at the scope seystem/services level.

 

/system/services # enter ip-block 0.0.0.0 0 https.

 

And finaly reimage the FTD with Gui.

FTD Virtual can not be a cluster, it can be active-standby and can be configured as transparent mode (this is most case in DC or want

to do in exiting network with out changing VLAN or IP address).

 

you need FMC for this to make it ( as per i know) - make sure you enable the interface before configuring.

 

here is the simple guide to guide :

 

https://www.cisco.com/c/en/us/support/docs/security/firepower-management-center/212699-configure-ftd-high-availability-on-firep.html

For Clustering, you need a Physical Kit and other requirements.

Hello Balaji

 

Thank you for your return.

 

Effectively I meant active/passive and thank you for the correction

 

Otherwise for the transparent mode in the above scenario, I wanted to know :

 

- How to declare all FTD interfaces connected outside or inside ? or that's just for the security part .

 

For the FMC it's essential I confirm, I used a 90 days license for the tests (LAB) but the interfaces don't want to go up.

Hello.

 

If i understand you correctly, you want delete current config from your FTD device via cli? Smth like "erase startup config" for cisco switches and routers and "reload". It this correct?

Hello

 

Not really, I have already deleted the config with the erase configuration command from the local-mgmt interface and now I can't reimage the ftd.

 

I am looking for the procedure to follow to restart the ftd.
